Contextuality Can be Verified with Noncontextual Experiments
Jonathan J. Thio, Wilfred Salmon, Crispin H. W. Barnes +2
We uncover new features of generalized contextuality by connecting it to the Kirkwood-Dirac (KD) quasiprobability distribution. Quantum states can be represented by KD distribution…
Convex roofs witnessing Kirkwood-Dirac nonpositivity
Christopher Langrenez, Stephan De Bièvre, David R. M. Arvidsson-Shukur
Given two observables and , one can associate to every quantum state a Kirkwood-Dirac (KD) quasiprobability distribution. KD distributions are like joint classical probabili…
Properties and Applications of the Kirkwood-Dirac Distribution
David R. M. Arvidsson-Shukur, William F. Braasch, Stephan De Bievre +6
Recent years have seen the Kirkwood-Dirac (KD) distribution come to the forefront as a powerful quasi-probability distribution for analysing quantum mechanics. The KD distribution…
